The material of core wire 51 is that alumel, chrome-nickel etc. are more crisp, is not that can bear to be used for bending of crimping etc. Material.In this case, fixed to the contact portion 20 being made of the alumel, chrome-nickel etc. by copper alloy Deng, be suitble to crimping material constitute connecting member 30, the connecting member 30 be arranged pressure contact portion 33.Therefore, according to this implementation The electric terminal 10 of mode, even the core wire of the more crisp material such as alumel, chrome-nickel also can reliably crimp fixation.
In this way, also using the electrical end with the electric terminal homotype in other side's electric terminal according to the electric terminal 10 Son can then not have to the electricity across other metals and by the alumel line or chrome-nickel line of thermocouple to be constructed from the same material The state of line extends to measuring instrument via electric terminal.
Fig. 6 is the perspective view of the electric terminal of the 2nd embodiment of the invention.Here, showing in the Fig. 6 and leading compensation Shape after the crimping of line 50.
In the case where electric terminal 10 of the 1st embodiment shown in FIG. 1 to FIG. 5, contact portion 20 is than connecting member 30 The insertion opening 31 of front end also protrude forwards.In contrast, the feelings of the electric terminal 10 ' of the 2nd embodiment shown in fig. 6 Under condition, contact portion 20 ' extends only into position identical with the front end of connecting member 30.The electric terminal of 2nd embodiment 10 ' only have the contact portion 20 ' different from the electric terminal 10 of the 1st embodiment.Therefore, in the Fig. 6, for implementing with the 1st The identical constituent element of electric terminal 10 of mode marks label identical with the label in Fig. 1~mark in Fig. 5 and is subject to It shows, saves more explanations to the construction of electric terminal 10 '.
It is not set to be inserted to other side's electric terminal in the case where the electric terminal 10 ' of the 2nd embodiment shown in fig. 6 The contact portion of the shape entered.The electric terminal 10 ' receives the male contact portion of other side's electric terminal (such as shown in FIG. 1 to FIG. 5 The contact portion 20 of electric terminal 10) insertion.Moreover, with the spring portion 32(of the electric terminal 10 ' with Fig. 3 together reference) make pair The contact portion of square electric terminal abuts to the contact portion 20 ' of the electric terminal 10 ', connects contact portion each other.
Fig. 7 is the perspective view of the other side's electric terminal combined with the electric terminal of the 2nd embodiment shown in fig. 6.
Other side's electric terminal 10 ' ' shown in Fig. 7, in the electric terminal 10 with the 1st embodiment shown in FIG. 1 to FIG. 5 Compared to when, there is the shape that spring portion 32 is removed from the connecting member 30 of the electric terminal 10 of the 1st embodiment.The other side is electrical Terminal 10 ' ' spring portion 32 other than constituent element it is identical as the electric terminal 10 of the 1st embodiment, to same element mark Same label and shown, save more explanations to the construction of other side's electric terminal 10 ' '.
In the electric terminal 10 ' of 2nd embodiment shown in Fig. 6, there is no the types being inserted into other side's electric terminal Contact portion.Therefore, in other side's electric terminal 10 ' ' and the not set electric terminal with the 1st embodiment shown in FIG. 1 to FIG. 5 10Spring portion 32(is referring to the corresponding construction of Fig. 3).But it as shown in fig. 7, is also required to crimp in other side's electric terminal 10 ' ' The construction of compensating wire 50.
In the case where electric terminal 10 of the 1st embodiment shown in FIG. 1 to FIG. 5, other side's electric terminal can also be used The electric terminal of homotype.Therefore, the component management of electric terminal becomes easy.But the electric terminal as thermocouple, one Male and female electric terminal of different shapes has been used since straight.Therefore, when following the habit, electricity for example shown in fig. 6 can be used The combination of gas terminal 10 ' and other side's electric terminal 10 ' ' shown in Fig. 7.
Alumel or chrome-nickel is used to be said as the example of contact portion 20,20 ' in addition, enumerating herein It is bright.But the metal material for constituting thermocouple is not limited to alumel and chrome-nickel.There is also use other gold for thermocouple The case where belonging to material.That is, the material as thermocouple, other than alumel or chrome-nickel, there is also use for example Constantan, nickel chromium triangle silicon (Nicrosil), nisiloy (Nisil), iron, platinum, platinum-rhodium alloy, iridium, iridium-rhodium alloy (イ リ ジ ウ system ロ ジ ウ System alloy), tungsten-rhenium alloy (タ Application グ ス テ Application レ ニ ウ system alloy), nickel chromium triangle, bule gold (golden iron alloy), nickel, nickel molybdenum close Golden (ニ ッ ケ Le モ リ Block デ Application alloy), palladium platinum alloy (パ ラ ジ ウ system platinum billon), rhotanium (golden パ ラ ジ ウ System alloy), the situation of gold cobalt alloy (golden U バ Le ト alloy) etc..Therefore, the contact portion as electric terminal of the invention, The case where in the presence of other metal materials are used.
In addition, be illustrated for the electric terminal of this measure thermocouple, but the scope of application of the invention is not It is only limited to thermocouple.For example, the case where in the presence of fine copper is used in order to flow high current.The fine copper is excessively soft, only pure with this Copper is difficult to constitute electric terminal.Therefore, the contact portion using fine copper as material is used, FIG. 1 to FIG. 5 or structure shown in fig. 6 are made The electric terminal made can also.
In this way, the present invention can be widely used in needing to use the metal for being difficult to only constitute electric terminal with the metal material Material carries out the case where reception and registration of electric signal, power transmission.
